Question

Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of the juice to mags. How much is left in luna's glass.

Answer 1

( 3/4 + 3/8 ) - 5/8

multiply 3/4 by 2 to make it 6/8

( 6/8 + 3/8 ) - 5/8

then solve the equation.

(6/8 + 3/8 ) - 5/8
9/8 - 5/8
4/8 or 1/2

Answer 2

3/4 = 4/8 (converting fractions )

4/8 + 3/8 = 9/8 cups of juice altogether

9/8 - 5/8 = 4/8 (taking away mags' amount )

4/8 is equivalent to a 1/2 so she still has 1/2 a cup of juice left.
